When I start up my computer it shows an error on a black screen that says: Boot device not found, please install an operating system on your hard disk.

I just try to open the recovery mode whit F11, but tough appears a text that says F11 recovery mode in the lower left corner nothing happens and the screen says another time the same error. Can anyone help me??

I have gone through your Post and would like to help

Please restore the BIOS back to default settings and check if that help

1. Turn off the computer and wait five seconds.

2. Press the Power button to start the computer and repeatedly press the F10 key to enter the BIOS setup menu.

3. On the BIOS Setup screen, press F9 to select and load the BIOS Setup Default settings.

4. Press F10 to Save and Exit.

5. Use the arrow keys to select Yes, then press Enter when asked Exit Saving Changes?

6. Follow the prompts to restart your computer.

If the issue persists run a Hard drive Test to confirm the Hardware Functionality

- Hold the power button for at least five seconds to turn off the Notebook.
- Turn on the computer and immediately press Esc repeatedly, about once every second. 
- When the menu appears, press the F2 key.
- On the main menu, click Component Tests and Hard drive

Keep me posted how it goes 😊
